halvorsen82 Posted July 6, 2006 Report Share Posted July 6, 2006 HiI've noticed in this late release that if I have several torrent downloading and I stop one of them all of my torrents downloading speed goes down for a while and then tuning up again. Is this a know "problem" ? Link to comment Share on other sites More sharing options...

halvorsen82 Posted July 6, 2006 Author Report Share Posted July 6, 2006 but what is the point? For me it seems silly Link to comment Share on other sites More sharing options...
Switeck Posted July 6, 2006 Report Share Posted July 6, 2006 It may be an artifact of how Windows closes out multiple ip connections at once, and as such something outside of µTorrent. Link to comment Share on other sites More sharing options...
halvorsen82 Posted July 6, 2006 Author Report Share Posted July 6, 2006 Well, I have not had this "problem" with earlier versions of u-torrent. It is therefor I ask... Link to comment Share on other sites More sharing options...
µtorrent-Guest Posted July 6, 2006 Report Share Posted July 6, 2006 and you have the up(!)loadline capable of downloading "several torrent" at once?! Link to comment Share on other sites More sharing options...

Switeck Posted July 6, 2006 Report Share Posted July 6, 2006 Ok, didn't have this problem before?Is this only with v1.6 you're now having this problem?Can you check with v1.5 if you still have it?Do you have UPnP and/or DHT enabled?What's your half-open connections set to?

halvorsen82 Posted July 6, 2006 Author Report Share Posted July 6, 2006 I don't have en ealier version of u-torrent to test with. I did not have the same problem with ealier versions, I installed u-torrent some days ago and saw that this happend every time I stop one torrent when others are running. UPnP port mapping is enabledDHT is enabledHalf-open connections? Sorry, doesn't know where to find that or what it is Link to comment Share on other sites More sharing options...
Switeck Posted July 6, 2006 Report Share Posted July 6, 2006 If you've done manual port-forwarding, you don't need UPnP -- that's just the automatic (and somewhat unreliable) equivalent.Half-open connections is set in µTorrent's advanced settings. The default value is 8, and it can cause major problems to set it higher on Win XP SP2 unless a special 3rd party patch is run on Windows.DHT uses UDP packets to share info about what torrents you have shared, and aquire the same from others. Unfortunately, it causes problems with any router or modem that's not completely reliable. Link to comment Share on other sites More sharing options...
halvorsen82 Posted July 6, 2006 Author Report Share Posted July 6, 2006 I have port forwarding in my router, so I turn off the UPnP thenHalf-open is set to 8.And I haven't had problems with this in ealier versions and I still use the same router as before:)But as kraijeck said it's normal(?) If this doesn't happens to others it may be soething on my computer. If not I think many others should aslo see the same thing... Link to comment Share on other sites More sharing options...
kraijeck Posted July 7, 2006 Report Share Posted July 7, 2006 Sorry for my first post. My English is bad.At first I understand that you Run 5-6 torrent and suddenly stop 1 torrent make TOTAL download speed wiil drop a little.That was I said it's Normal. I'm Sorry.But now I know what you mean is EVERY torrent speed drop a little.Try to Patch TCPIP.sys and set net max halfopen = 64 Link to comment Share on other sites More sharing options...
Switeck Posted July 7, 2006 Report Share Posted July 7, 2006 I would think having half-open connections set rather high would make this problem worse instead of better.Presumeably, any already-running torrents easily have enough peers/seeds already connected. So when you stop 1 torrent, ALL the peers/seeds you still have connected on the other torrents should be readjusted in speed to pick up the slack...should stabilize out at the new value in 5 seconds or less. However for those 5 seconds, closing out all the old torrent's connections may be causing some problems.Madly opening LOTS of new connections (which is setting half-open connections higher is doing) would make that take longer and cause a harder hit in download speeds when 1 torrent is stopped.

Firon Posted July 11, 2006 Report Share Posted July 11, 2006 Stopping/starting a new torrent generates a bunch of TCP traffic due to closing/opening connections. That's why. Link to comment Share on other sites More sharing options...
